Euro got it right, the main reason you see the modded zx3s whooping up on svt's is because of the transmission. the svt is NOT geared for straight line acclereation. put that same modded zx3 against the svt in an autox, the zx3 will have his a** handed to him. it's all in the gearing. the dual stage manifold on the svt and the variable cam timing offer more potential for naturally aspirated applications than the zx3 parts, but due to the higher compression of the svt, you can't run a lot of boost on pump gas, which is why the zx3 typically sees more power with FI. but put some low compression pistons in an svt, put in a better manifold for FI (use a standard mani), slap a turbo on there, and tune the hell out of it, and it'll show much better numbers than the zx3 due to the VCT and higher redline.
